SMOOTH-ROPE AND KN OTTED-WIRE CHECK-ROWER.

, SPECIFICATION forming part of Letters Patent No. 278,622, dated May 29, 1883.

Applicationfiled February 10,1883. (No model.)

I To all whom it may concern:

Be it known that 1, DANIEL SPooNna, re-' siding in the town of Blue Mound, in the county of Macon andState of Illinois, have invented a new and useful Improvement in Smoothltope and Knotted-Wire Check-Rowers, of which the following is a specification, reference being had to the accom panying drawings and lettersZof reference marked thereon,

in which- Figurel is a plan view of my smooth-rope check-rower. Fig. 2 is a side elevation of the same, and Figs. 3 and 4 are detail views.

My invention relates to improvements in smooth-rope and knottedwire check-rowers; and it consists in the peculiar construction I and arrangement of the parts, as hereinafter more fully set forth, and pointed out in the claims. I In the accompanying drawings, G G represent two semicircular cam-plates, the planes of which are inclined to each other and joined togetheralong their common diameter, provided with a longitudinal opening for the reception of the shaft 0, keyed thereto.

F represents a post adjustably secured to the lower face of the measuring-wheel A, over the semicircular cam-plates G, by means of nuts, and providedat its lower end with a friction-wheel, 1), adapted, in the revolution of the measuring-wheel, to be brought to bear first on one and then on the other of the semicircular cam-plates G, and thus imparta rocking motion to the shaft 0. The semicircular cam plates G, secured together with their.

. planes .inclined to each other, thus form a eradle, D, rocked back andforth by meansof the post F and its friction-wheel b at each revolution of the measuring-wheel A. The postF is made adjustable in its length by nuts, to com pensate for any wear on the cradle. The "fIiCtlOlI-WhBBl 7) travels over each semicircular cam-plate G of the cradle D alternately in and the slide-bar of the planteris made by the slotted arm I, provided with a wrist-pin. Two forks or clutches set into the periphery of the measuring-wheel, and flush with the outer surface of the same, and atexactly opposite points of diameter, and the side pulley,may be I wheel power is gained in working the seedsli'de, and the jerking common to a knotted rope and wire check-rower is obviated.

it is designed in this invention to provide for drilling seed as well as planting. To accomplish this result the cradle D is detached, and a system of cams, G, adjusted in such a manner as to receive motion from correspond ing posts, F, carrying friction-wheels attached to the alternate arms of the measuring-wheels A at varying distances from its center, so as not to conflict with each other in reversing the in contact with the measuring-wheelA by means of the spring K.

11 represents an angular* bar extending across and under the wooden bar N, at right angles thereto, and supporting. said bar and the parts resting thereon, one of the upright arms of the angular bar H provided witha horizontal arm, 0, having a recess in which the slide J, carrying the wheel B,operates, the

latter being always pressed against the circum- 5 ference of themeasu'ring-whee lrA by the spring K, to prevent the rope]? from slipping.

. Having thus fully described my invention,

what I claim as new, and desire to secure by Letters Patent, is:-

1. The combination,witha measuring-wheel, of a cradle, D,constructed substantially as dc too 75 cams and to Imparta reciprocating movement scribed, and adapted to impart a reciprocating motion to a seed-slide, as set forth.

2. The combination, with the measuring- Wheel A, provided with the post F and friction-wheel b, of the cradle D,rock-shaft O, and

slotted arm I, provided with awrist-pin adapted to be attached to a slide-bar, substantially as described, and for the purpose set forth.

3. The combination, with the grooved measuring-wheel A and its rope P, of the angular bar H, having the horizontal recessed arm 0, secured to the upper end of one of its uprights, slide J, carrying the Wheel B and adapted to move in the recess in the arm 0, and spring K,

secured to one end of the slide and to the up- 1
